------------------------------------
Summary: Invalid subscription data may cause streams app to throw
BufferUnderflowException
Key: KAFKA-5625
URL: https://issues.apache.org/jira/browse/KAFKA-5625
Project: Kafka
Issue Type: Bug
Reporter: Xavier Léauté
Priority: Minor
I was able to cause my streams app to crash with the following error when
attempting to join the same consumer group with a rogue client.
At the very least I would expect streams to throw a {{TaskAssignmentException}}
to indicate invalid subscription data.
